How a Bill Becomes Law: A Simple Student Guide

The seven stages, start to finish

1. 1. IntroductionA member of the House or Senate introduces the bill. It gets a number (H.R. or S.).
2. 2. CommitteeThe bill is referred to a committee that specializes in the topic. Most bills stop here. (See: "Referred to Committee".)
3. 3. Committee approvalIf the committee holds hearings, amends, and votes to advance it, the bill is "ordered to be reported" to the full chamber.
4. 4. First chamber voteThe full House or Senate debates, may amend, and votes. A simple majority passes it.
5. 5. The other chamberThe bill repeats the whole process in the second chamber. Both chambers must pass identical text — differences are resolved in a conference committee.
6. 6. The PresidentOnce both chambers pass the same bill, it goes to the President, who can sign it into law or veto it.
7. 7. Veto override (if needed)If the President vetoes, Congress can override with a two-thirds vote in both chambers — a high bar that rarely happens.

Why so many bills fail

Each stage is a filter. Of the thousands of bills introduced in a typical Congress, only a few percent become law. Most die quietly in committee, never scheduled for a vote. That is by design: the process is built to make passing a law difficult, so only proposals with broad support get through.
